RELAY ARRAY FOR GRID CONNECTION |
(57) A relay array may connect an electrical device (e.g., an inverter, power converter,
etc.) to a utility grid. Based on a detection of a power interruption or fault, the
relay array may disconnect the electrical device from the grid to ensure safety or
reduce damage to the electrical device or grid. The relay array may include one or
more latching relays. A safety catch may prevent the latching relay(s) from changing
states. The electrical device may be configured to facilitate removal of the safety
catch once the ability to change states is desired. The latching relay(s) may also
be supplied with a power pulse for changing a state of the latching relay(s). The
power pulse may be provided by a power bank that may be maintained with power in case
of a power interruption or fault.
